Hobbit homes remain on the farm in New Zealand.
Although it's mostly sheep inhabiting them now.
Funny by the way how Lord Of The Rings is not just popular, it's so big, mental-impact-wise, that virtually all fantasy since it have been caught in its gravity field, creatively. I personally really don't get the attraction. But there must be something about it, I personally have two friends for whom LOTR is the one book they can and will read and read and read again.
Granted, I'm more of a SF guy than a fantasy guy. But maybe that's because almost all fantasy is "high fantasy" (a nicer word for LOTR rip-off). I like fantasy if the author steps out of the cookie cutter, for example Tim Powers, his books Anubis Gates and Last Call are amongst my favorites, they are fantasy, and they have all-original ideas throughout, not a tall hat with stars on it in sight.
Update: I have just found out that four of Tim's books are on Audible/iTunes! Zippidy. I may start with On Stranger Tides (review), which is one I haven't re-read since back then. (Note, if you're not in the US, you need an American credit card to get the audible version, typical silly territorial issues.) Oh, and they are narrated by Bronson Pinchot... remember the genius who played Serge in Beverly Hills Cop? The faux-French, faux-gay, faux-everything hilarious art gallery clerk. I wonder what happened to him, film-career wise, he was outstanding.
